STRIP.

Application filed January 2, 1925. Serial No. 258.

My invention relates to improvements in Weatherstrip. One of its objects is to pro-- vide an improved all metal Weatherstrip. Another object is to provide an improved Weatherstrip having a more uniform resilient tension over a wide range of adjustments, whereby a long period of uniform resiliency in use is insured. Another object is to provide an improved form of metal weatherstrip, whereby improved and continuous close contact is maintained the full length of the joint. Another object is to provide normally for a doubly sliding or surface contact at the joint. Another object is to provide a Weatherstrip in which there is an improved metal to metal sliding contact. Another object is to provide a Weatherstrip better adapted to exclude wind and water. My invention also comprises certain details of form, and combination and arrangement of components, all of which will be fully set forth in the description of the accompanying drawings, in which Fig. 1 is a perspective view of a section of metal Weatherstrip embodying my invention.

The accompanying drawings illustrate the preferred embodiments of my invention in Figs. 1, 4i and 5 of which the Weatherstrip is constructed by curving the middle section of a strip of resilient sheet metal, bending the metal upon itself at 16 to provide a section of double thickness by means of which the strip is designed to be attached to one of the joint members. The edge or section 17 of the strip outside of the section 16 is bent at an obtuse-angle relative to the section 16 outwardly or away from the section 15. At the opposite side of the section 15 the metal is bent upon itself to form a section 18, the outer edge of which is designed to contact with the opposite joint member to that to which the section 16 is attached. The edge or section of the strip 19 outside of the section 18 is bent at an obtuse angle to section 18, so as to extend outwardly or away from the section 15. The width of the sections 17 and 19 is preferably such that their adjacent edges overlap and in operation form a sliding joint between said members with the section 17 resting resiliently against the face of the joint member 20 to which the section 16 is attached, while the section 19 at its free edge rests resiliently against the inner face of section 17, and is free to slide transversely thereof to a greater or less extent as the Weatherstrip is compressed between the joint members 20 and 22. As shown in Fig. 4, the Weatherstrip is mounted in a relatively narrow spacebetween the window frame or joint member 20 and the window sash or joint member 22. In Fig. 5 is shown the relative position of the sections of the strip where the strip is mounted in a relatively wider space between a window frame 20 and a window sash 22. The section 16 is preferably provided with a series of perforations 24 at intervals to facilitate the attachment of the strip to the Window frame for instance. In order to facilitate the sliding of the edge of section 19 transversely of the section 17, I preferably slightly inwardly curve the free edge 25 of section 19. If desired the free edge of section 17 may also be slightly curved inwardly or away from the joint member 20, to a less extent than section 19, to facilitate the slight movement of the free edgeof section 17 transversely of joint member 20 as the result of changes in compression applied to the strip as the sash 22 is moved up or down. It will be noted that in Fig. 5 the strip section 15 is entirely out of contact with the sash 22, and only Ill;

the end of the strip section 18 is in contact with the sash, while in Fig. t the curved middle portion of section 15 as well as tl e end of section 18 is in contact with the sash 22.

in the modification Fig. 2, the middle'section 27, of the strip, corresponding to the section 15 of Fig. 1, is flat instead of being curved as in Fig. 1. The sections 28 and 29, corresponding respectively to sections 16 and 18 of Fig. .1, are substantially as heretofore described for Fig. 1. The sections 30 and 31, corresponding respectively to sections 17 and 19 of Fig. 1, are substantially the sameas heretofore described for 'Fig. 1, exceptthat the major portion of said sections are in substantially the same plane with the sections 28 and 29 to which they are respectively connected, instead of being bent to an obtuse angle relative thereto The modification Fig. 3 is substantially the same as that shown in Fig. 2, except that the sections 33 and 3 1, corresponding to the sections 30 and 31 of Fig. 2, are relatively more narrow than the sections 30 and 31, and the corresponding sections 17 and 19 of Fig. 1, and hence the free ends of the .ections 33 and 3% do not engage or overlap one another, and do not have sliding relations one with another. Instead the sections 33 and 34 each independently engage the joint member 35 to which the strip section 36 is attached by nails or screws 37, see Fig. 7.

In Fig. 6 I haveshown the strip Fig. 2 applied to a joint between a door frame 38 and door 39, in which the strip is attached to the door frame by means of nails or screws 40, passed through the strip section 28, allowing the doorto open and'cl'ose, and the end of section'29 to engage the edge of the door when the door is closed.

between a window frame 42 and a window sash having a relatively wide joint space.

Fig. 9 illustrates a section of the strip Fig. 2, in which a notch or recess 14lhas been cut through a portion of the section 27, and

I either a .door latch or a door bolt.

noted however that due to the bending of tin.

sections 17 and 19 at obtuse angles to the sections 16 and l8,the section 17 is pressed with a greater degree of resiliency against the face-of the sash 20, andthat the section 19 bears against the inner face of section 17 with a greater degree of resil- Fig. 8' shows a strip Fig. 2 applied to the joint iency, and that where the joint space is rel atively narrow as in Fig. 1, the contact of the curved face of section 15 with the sash 22 serves to increase the contact with the sash, and at the same time reacts to increase the resiliency with which the section 19 bears upon the inner face of section 17. Hence the strip Fig. 1 is believed to be preferable for the purpose, and to have a wider range of resilient tension and adjustment.

The overlapping of the edges of sections 17 and 19 of Fig. 1, and of sections 30 and 31 in Fig. 2, provide smooth metallic faces along which the edges of sections 19 and 31 slide in maintaining tight joints automatically, and obviate liability of the edge'of the metal being caught on'the rough wooden faces of the window frame or sash, to prevent such sliding action taking place when required. The overlapping of the sections 17 and 19, and 30 and 31 also serves to greatly strengthen the strips for shipment and handling prior to being attached to the window or door frames, and facilitates recessing for door latch and bolt without opening air passages. The modification Fig. 3 also possesses to a large degree the above mentioned advantages.

in operation the leverage exerted by the sash is applied chiefly to the extreme end of section 18, where the widestrange oi movement of the strip would be capable of taking place. The resilient action of sec tion 19 tends to counteractthe pressure of the sash, which results in the resilient tension of member 18 against the sash remaining nearly constant whether the joint'space is wide or narrow, and in general gives a wide range of adjustment tothe strip without straining any member of the strip to a point to tan its moment of resiliency and thus cause it to take a permanent set or bend, hence the strips tend to perform their functions and to retain substantially all of their original resiliency for long periods of useful service.

An important advantage of the inwardly turned sections 17 and 19, and corresponding sections of Figs. 2 and 3 is that said sections being extended or directed toward the center of the strip from the nails or screws by which the. strips are attached to the window frame, and bearing resiliently against the window frame or corresponding joint member, there is practically no tendency for the strip to cook up in the neighborhood of the nails or at any point along the strip section 16 of Fig. 1 or corresponding sections of Figs. 2 and 3, or to tend to pull the nails endwise from the window frame. thereby enabling the nails or screws to be spaced at relatively wide distances apart. The bending of sections17 at an obtuse angle to section 16 facilitates Wide'spacing of the nails, and prevents canting or lifting llU Ill

of section 16 away from the face of the window frame. If desired sections 30 and 31 of Fig. 2, and corresponding sections of Fig. 3 may be bent to obtuse angles as shown in Fig. 1. The curving of section 15, and the turning inwardly of sections 17 and 19 and corresponding sections of Figs. 2 and 3 tend to prevent bending or buckling of the strips. My improved strips enable superior contact to be made with opposite faces of the joint.

In the modification Fig. 10, Ihave shown a section 50, corresponding in a general sense to the sections 17 30, and 33 of Figs. 1, 2, and 3, except that the width of section i or portions thereof has been increased to such an extent that it extends beyond the end of the section 18, for instance, and is adapted to act as a spacing gauge to prevent the Weatherstrip being nailed in place with the end of section 18 so close to or close enough to the window frame section 51 to cause the end of section 18 to contact with the face of section 51 when the sash is inserted and the Weatherstrip is compressed,

which is liable to happen when the strips are applied by inexperienced persons. The extension of section 50 or portions thereof beyond the end of section 18 insures placing the edge 52 of section 50 inside of the face of section 51 and thereby insures that even when the strip is fully compressed, the edge of its section 18 shall clear the face of the window frame section 51 under all conditions of use.

The apparatus herein shown and described is capable of considerable modification within the scope of the claims without departing from the spirit of my invention.

V hat I claim is:

.l. A Weatherstrip comprising a strip of resilient material folded longitudinally thereof face to face upon itself to form an intermediate sect-ion with double thick sections at opposite edges thereof, and two inwardly turned sections extending from the inner edges of said double thick sections and diverging from said intermediate section at acute angles.

2. A Weatherstrip comprising a strip of resilient material folded longitudinally thereof face to face upon itself to form an intermediate section curved transversely of its length with double thick sections at 0pposite edges thereof, and two inwardly directed sections extending from the inner edges of said double thick sections at acute angles to said intermediate section.

3. A Weatherstrip comprising a strip of resilient material folded longitudinally thereof upon itself to form a first intermediate section, second and third double thick sections at opposite edges of said first section, and inwardly turned fourth and fifth sections each diverging from the inner edge of a double thick section at an acute angle to said first section, the free edges of said fourth and fifth sections overlapping one another and adapted to slip transversely of their length one upon the other.

1. A Weatherstrip comprising a strip of resilient material folded longitudinally thereof upon itself to form a first intermediately located section, second and third double thick sections at opposite edges of said first section, and inwardly turned fourth and fifth sections diverging respectively from the inner edges of said double thick sections at an acute angle to said first section, the free edge of one of said last named inwardly turned sections being curved and overlapped by the free edge of the opposite inwardly turned section to provide for a relative sliding movement transversely of the length of said inwardly turned sections.

5. A 'weatherstrip comprising a strip of resilient material folded longitudinally thereof face to face upon itself to form a first section of double thick material adapted to be attached to the face of a first joint member, second and third leaf sections extendingfrom one edge of said double thick section and diverging one from the other at an acute angle, the second section serving to resiliently engage a second joint member to form a weatherproof joint therewith while said third section serves by engagement of its free edge with said first joint member as a spacing gauge to insure initial location of said Weatherstrip with sufficient space in which said second leaf section may move to perform its function.

6. A Weatherstrip comprising a strip of resilient material folded upon itself to constitute a first intermediate section, second and third double thick sections at opposite edges of said first section, a fourth gauge section and a fifth resilient supporting section, said fourth and fifth sections being inwardly turned from the inner edges of said second and third sections and diverging from said first section at an acute angle thereto, the width of said fourth section being greater than the width of said first section.

In testimony whereof, I have hereunto afiixed my signature.
